Introduction –
Network latency and Bandwidth are the two metrics most likely to be of interest when you benchmark a network. Even though most service and product advertising focuses on bandwidth, at times the latency can be a more important metric.

** What is Bandwidth?

Bandwidth (BW) in computer networking refers to the data rate supported by a network connection or interface. BW is measured in terms of bits per second (bps).

** What is Network latency?

Latency is a measure of time delay experienced in a system. Network latency is simply defined as the time delay observed as data transmits from one point to another. There are a number of factors that contribute to network latency. These include transmission(medium of connectivity), Distance, Routers and computer hardware delays.
